GERMANY, A CORPORATION ANODE FOR ELECTRIC VACUUM APPARATUS.

Patented Jan. 6, 1920.

Application filed September13, 1916. Serial No. 119,883.

To all whom it may concern:

Be it known that I, MORITZ Sonnnnsna German citizen, and resident ofCharlottenburg, near Berlin, Germany, have invented certain new anduseful Improvements in. Anodes for Electric Vacuum Apparatus, of

which the following is a specification.

My invention relates .to electric vacuum apparatus and more especiallyto anodes for use in apparatus of this class such as mercury vaporrectifiers.

United tates led by Joseph Just and myself, Ser. No. 114,644, relatingto electric vacuum apparatusan annular anode of this class was describedand claimed. The present invention contemplates providing an annularanode which is built up from a number of. annular sections some of thesesections being anodes and the rest being part1- tions adapted toseparate these sectional anodes from each other, the whole forming aself-contained anode body adapted to be easily put in'place and to beremoved from the vacuum vessel as a whole. In the drawings accompanyingthe specification and forming part thereof,

Figure 1, shows the preferred form of an anode according to my inventionas applied to a mercury vapor rectifier, the figure showing one half ofsaid rectifier and anode in vertical section. I

Fig. 2, shows a modification of the anode structure.

Fig. 3, thereof. i

Referring to Fig. 1 of, the drawings 1 is the rectifier vessel, 2 is itscover, 3 is a seal securing an airtight fit between the vessel andcover. 5, 6, 7 are three annular anodes, 8 is a conductor adapted toconduct the elecshows a further modification tric current to said anodesand to feed a cooling medium such aswater into channels provided to thisend within said anodes. In.

the case where the individual anode rings present different phases, anumber of current coluluctors corresponding to the number of differentphases should be provlded' and connected with the respective anodes.-

9 is a seal interposed between the cover opening and the conductorassing through it. 20 is a mercury catho e WlllCh m ght however bereplaced by a cathodeof any other suitable kind such as for instance aglow cathode of a suitable form. 1

In a prior a plication for patent of the 14, 15 and by screw bolts 16,place resisting insulating material such as porcelain, these samepartitions being interposed between-the anodes aswell as between thelower and upper anode and the plates lel and l5 respectively which tendto press the partitions and anodes tightly together under the actlon ofscrew bolts such as 16. By aid of these pressure plates and bolts theanode rings and partitions are made to form a compact self-sustainingbody adapted to be removed from the rectifier vessel as a whole afterthe cover 2 has been removed.

The periphery of the lower pressure plate 14 rests on a shoulder 17provided within the rectifier vessel, said shoulder preferably servingto render the chamber formedbelow said pressure plate tight so that inthe case, where the upper partition 13 has the form of a solid plate,the space left between said plate 13 and the cover 2 of the vesselformsa separate chamber not connected with the vapor chamber proper andadapted to be used as a preliminary vacuum chamber.

As shown in the drawings the partitions 11 and 12 as well as thelowermost partition 10 may be bent or curved downward or else theircenter part may carry metal cylinders 10*, 10, such cylinders beingpreferably inserted in annular grooves 18,.19 of said partitions such asshown in Fig. 2. In the case where annular anodes of a differentdiametc!" are employed, the whole'anode assumes the form of a cone, thediameter of the an So far as the scope of the invention goes, it is ofcourse, also possible instead of placing the faces of the anodes whichare struck.

by the are, on the inner side of the anode rmgs, to place them so thatthey are'facing outwardly. This modification is shownin Fig. 3, whereannular anodes 5*, 6, 7 are inserted between the hell-shaped partitions10 11, 12* and 13*, the entire system being held together with the aidof rin plates 5 in this case on the .inside of the anode ring. Theconductor 8 in this case is also placed and connected to the anode atthe inside of the ring as shown in Fig. 3.

I claim 1. An anode for electric vacuum apparatus composed of aplurality of anode rings and atleast one partition separating said ringsfrom each other.

2. An anode for electric vacuum appara tus composed of a plurality ofsuperposed v anode rings and at least one partition separating saidrings from each other. v i

3. An anode for electric vacuum apparatuis composed of a plurality ofanode rings and at least one annular partition separating said ringsfrom each other.

4. An anode for electric vacuum apparatus composed of a plurality ofsolid annular composed of a plurality of anode rings of equal diameterand at least one partition separating said rings.

7 In electric vacuum apparatus, in combination a vacuum vessel and aself-sustaining anode body of substantially cylindrical shape, composedof'a plurality of individually active anode elements and disposed Withinsaid vessel.

8. In electric vacuum apparatus, in comblnatlon a vacuum vesseland aself-sustaining'anode body of substantially cylindrical shape, composedof a plurality of individually active anode elements removably arrangedWithin said vessel.

9. In electric vacuum apparatus in combination a vacuum vessel and aplurality of annular anodes and of partitions between said anodesremovably arranged within said vessel.

10. A self-sustaining anode body, comprising in combination a pluralityof solid annular anodes and partitions alternately disposed one abovethe other and means for holding said anodes and partitions together. 11.A self-sustaining anode body, comprising in combination a plurality ofsolid annular anodes and bell-shaped partitions alternately disposed oneabove the other and means for holding said anodes and said partitionstogether.
